We tested whether Hooded Warblers (Wilsonia citrina) experienced a smaller food supply in small versus large forest fragments in northwestern Pennsylvania. Using 16 fragments that ranged in size from 0.7 to 214 ha, we videotaped parental feeding rates to nestlings in 35 nests and sampled arthropod abundance on 24 breeding territories. Contrary to our predictions, neither feeding rate per nestling nor arthropod abundance on breeding territories was significantly less in small (<4 ha) versus large (>150 ha) fragments. Brood loss due to starvation was rare and overall nest success was not significantly less in small fragments. Similarly, prey size delivered to nestlings and arthropod size sampled on territories did not differ significantly between fragment size classes. We conclude that Hooded Warblers breeding within small forest fragments in the northwest Pennsylvania landscape do not suffer from a relatively small food supply.
